Abstract
Description
- The invention relates to a device for the conveying of sheets to a processing station, comprising at least two stock holders for sheet piles, in which each sheet pile is provided with a separation roller which can be activated selectively in order to convey a sheet from a stock holder to a processing station, and conveyor tracks provided with conveyor elements which connect the stock holders to the processing station. Such a device is known from the Netherlands patent application 7404899.
- A device is described therein which is provided with a number of stock holders with means forming part of each stock holder to separate a sheet from the pile included therein and means to convey that sheet to an exposure station. The feed from the various stock holders to the exposure station is effected according to the abovementioned Netherlands patent application 7404899 via entirely separated conveyor tracks. The feed of sheets via entirely separated conveyor tracks has as a disadvantage that a large number of conveyor and driving means are required, which requires a complicated sheet feeding system requiring a lot of space.
- The object of the invention is to provide a conveying device for sheets which does not have the abovementioned disadvantage, and which is able to convey sheets with a relatively small number of conveyor and driving means from one of a number of stock holders to a processing station.
- According to the invention this object is achieved in that the conveyor track for each stock holder which is situated nearer to the processing station coincides with a part of the conveyor track for each holder situated further away from the processing station, in that the conveyor elements at least partially consist of roller pairs of which each time the driven roller is formed by a separation roller and in that when one separation roller is activated, all rollers are driven in a rotating way. In this manner it is achieved that with a relatively small number of conveyor and driving means sheets from one of a number of stock holders can be conveyed to a processing station in such a way that a simple sheet feeding system taking little space is created..
- Preferably, each separation roller in a non-activated position is not in contact with the sheet pile and means are available which when the separation roller is activated, effect a contact between the separation roller and the sheet pile.
- In this way it is achieved that with simple means it is guaranteed that sheets can only be fed from the selected stock holder. Preferably the sheet pile at least partially rests on a movable plate which has been fitted against a wall of a space which can be connected to a compressed air source and discharge openings are formed in the wall.
- In this way it is achieved that each separation roller can be installed in a fixed position and that the sheet pile forming part of the activated separation roller can only come into contact with the separation roller during excitation by compressed air.
- Preferably the separation roller is formed by a suction roller. In this way it is achieved that during the separation a sheet can simply be kept in contact with a circumferential part of the separation roller in order to be able to branch off the sheet in the conveyor track formed by roller pairs.
- Preferably the suction roller is formed by a hollow cylindrical tube which on the outer surface is provided with a coating in which a number of borings have been fixed, the borings being connected to the space inside the hollow tube via a number of saw cuts fitted perpendicularly to the axis of the tube, of a depth which is smaller than half the diameter of that tube.
- In this way it is achieved th.at a simple constructed suction roller is obtained which at the same time can function as a friction conveyor roller.
- Other characteristics and advantages of the invention will become clear from the description given below of a preferred embodiment reference being made to the attached drawings, in which:
- Fig. 1 is a diagrammatic cross section of a number of stock holders situated above one another,
- Fig. 2 is a diagrammatic cross section of a part of an electro-photographic copying machine, in which a device for the conveying of sheets according to the invention, can be used,
- Fig. 3 is a cross section of a stock holder with connected air pressure system,
- Fig. 4 is a longitudinal section of a separation roller,
- Fig. 5 is a cross section of a separation roller according to line V-V of Fig. 4, and
- Fig. 6 is a slide axially shifted in two positions which can be fitted in a separation roller.
- Fig. 1 shows a cross section of a number of
stock holders - In fixed positions, at some distance above the discharge side of each sheet pile a
separation roller joint conveyor track 9 which extends almost vertically alongside the discharge side of the stock holders. The conveying of sheets in this conveyor track is obtained bypressure rollers separation rollers - As shown in Fig. 2, which represents an electro-photographic copying machine in which the invention can be applied, the
separation rollers joint drive element 14 which i's kept in motion by adrive motor 15 when the device is switched on. A sheet supplied by the abovementioned roller pairs vi'aconveyor track 9 is fed to anendless conveyor belt 16 which extends horizontally above the stock holders.Conveyor belt 16 can be driven in two directions bymotor 15 via a transmission anddrive element 17. - The flat part directed upwards of
conveyor belt 16 forms the exposure place of fed photoconductive receiving sheets. Acharging unit 18 is placed above theconveyor belt 16 in a fixed position which is situated upstream of the exposure place. When the charging unit is in operation a fed photoconductive receiving sheet reaches the exposure place in a charged condition. The receiving sheet is kept in the desired exposure position by interrupting the drive ofconveyor belt 16. - By means of an optical system not-shown an image-of an original, for instance a microfilm, can be projected onto a receiving.-sheet positioned in the exposure plane in order to form a latent electrostatic image thereon. Upon further conveying from the exposure position the receiving sheet is guided part a developing
device 19 in order to develop the latent charge image. - In order to enable the operator to carry out the optical adjustment on a sheet positioned in the exposure position it is desirable that a photoconductive receiving sheet can be brought into the exposure position in an uncharged condition.
- After this adjustment has been carried out, the receiving sheet concerned can still be charged by moving the conveyor belt in the opposite direction until the receiving sheet has passed the charging device entirely, after which the receiving sheet, with the charging unit switched on, is again fed to the same exposure position. In order to avoid during the returning conveying that the receiving sheet arrives in the
vertical conveyor track 9, a branching element 20 is brought into the dotted-line position during this conveyance. - At the same time an air stream from space 21 is directed at the receiving sheet in order to guide it over a
plate 22 which has been fitted underneath theconveyor belt 16. After exposure of a charged receiving sheet,conveyor belt 16 takes the receiving sheet provided with. a latent image to a developingdevice 19, after which the finished copy leaves the copying machine. - The position which a receiving sheet can occupy in the exposure plane is adjustable, for instance depending on the si'ze of the fed receiving sheet or on the desired position of the projected image on the receiving sheet.
- Seen in the direction of movement a positioning is obtained by stopping the movement of the
conveyor belt 16 at the moment that the receiving sheet has reached the desired position. - In the direction perpendicular to the direction of movement a positioning can be obtained by fixing the stock holders i'n the copying machine movably in that direction.
- The effective operating area of the
separation roller - The stock holders can if necessary be moved in a transverse direction up to outside the machine, in order to make them accessible for putting in a new pile.
- The new invention will now be further described on the basis of Fig. 3, which shows a stock holder. The other stock holders are built up analogously. Each stock holder is formed by a
bottom plate 23 and a raisededge 25 on the discharge side. - The bottom plate is provided with
openings 24 near the discharge side. Part of thebottom plate 23 and the raised edge are double-walled to form an enclosedspace 26. This space is limited on the underside by a V-shaped part 27 which is provided with openings 28. Raisededge 25 is provided withopenings 29 in the wall directed to the pile and in fact at the height of the upper side of an inserted sheet pile. The stock holder can slide with the V-shaped part 27 over acylinder 30 fitted in a fixed position and which is provided withopenings 31. Theseopenings 31 form together with openings 28 a connection betweencylinder 30 andspace 26. The cylinder is, via a compressed air line, connected with acompressed air source 33, so that viaopenings 31 and 28 an increased air pressure can be achieved inspace 26. - With bottom plate 23 a
cover plate 31 is connected by hinges. The hinges can be formed by a flanged edge 32 of the bottom plate, which protrudes through openings fitted in the bottom plate.Cover plate 31 carries a part of the inserted pile and covers in the rest position theopenings 24 fitted inbottom plate 23. When an increased air pressure is effected inspace 26, the air flowing throughopenings 24 will press upcover plate 31, as a result of which the top sheet of the pile resting on this will be brought into contact withseparation roller openings 29 in the raisededge 25 of the stock holder, air is blown against the front of the pile in order to detach the leading edges of the sheets from one another. - Each
separation roller air source 33. - According to Figs. 4 and 5 each separation roller is built up from a hollow
cylindrical tube 34 provided withopenings 35 obtained by saw cuts and covered by asheath 36 of resilient material, for example rubber, provided withopenings 37 which are connected toopenings 35 in the tube. One tube end is linked to the suction line ofcompressed air source 33 in order to create underpressure in the roller. A roller thus built up may function as a friction conveyor roller and as a suction conveyor roller. - Each separation roller is preferably of the same length. This has its advantages in connection with the manufacture and assembly between the same frame plates inside a copying machine. If a separation roller has to cooperate with a narrower sheet pile, the suction width of the separation roller to the pile width may be limited by bringing a hollow
cylindrical slide 38 into the roller. This slide shown in Fig. 6 in two positions is provided withslots 39 running parallel to the rotation axis at the length of the pile width. Only at the places of these slots the separation roller will be able to work as a suction conveyor roller. By axial shifting of the slide in the separation roller the suction area of the separation roller can be shifted depending upon the position of the stock holder. - On the basis of Fig. 3 the removal of a receiving sheet from the pile in accordance with the invention will now be described.
- A compressed air source creates simultaneously an underpressure in
line 40 and an overpressure inline 41. When a sheet has to be removed from the pile, two valves are simultaneously opened invalve block 42 in order to effect simultaneously an underpressure in one of theseparation rollers cylinders 30 in aspace 26. - As a result of an increase of the air pressure in this
space 26 thecover plate 31 moves upwards, so that the pile resting thereon comes into contact with aseparation roller openings 29 in the raisededge 25 of the stock holder air is simultaneously blown against the discharge side of the pile in order to prevent that more than one sheet is carried off by the separation roller. The separation roller keeps one sheet sucked up for at least one quarter of a revolution until the leading edge has come into contact with the pressure roller which cooperates with the separation roller. At that moment the valves concerned invalve block 42 close, as a result of which the pile returns again to its original position and the separation roller no longer functions as a suction roller. The roller pairs formed by a separation roller and a pressure roller operate further as friction conveyor rollers in order to convey receiving sheets taken from piles situated lower to a processing station. - It is clear that the invention is not restricted to the embodiment described above, but that within the framework of the invention numerous modifications are possible. It is possible, for instance, to effect the briefly required overpressure in
space 26 and the simultaneously briefly required underpressure in one of theseparation rollers
